Abstract
In an electrophotographic recording method in which electric charge is uniformly applied to the surface of a photoconductive drum, the drum surface is then exposed to a first information light beam to form a first negative latent image, the first negative latent image is developed with a first two-component developer, the drum surface is further exposed to a second information light beam to form a second negative latent image, and the second negative latent image is developed with a second two-component developer to produce a two-color toner image, the toner content in the second two-component developer is larger than that in the first two-component developer.
